Technical field:
The invention relates to a kind of manufacture method with heat storing and heat preserving functional polyester.
Background technology:
The heat of people's health is owing to radiation, convection current, conduction or other modes constantly run off, so people constantly use variety of way to prevent human heat's loss.As people's thick web on the top layer of heat-insulating and cold clothes and nexine therebetween, be the inside that the lower air of thermal conductivity can be kept at clothes, for example: wadded jacket, insulated cold wear etc., unusual heaviness but this kind clothes wear, not only be unfavorable for activity, and not attractive in appearance.Have the material that some reflectivity are stronger to be coated on the cloth of internal layer again, in case the scattering and disappearing of body heat, but this kind method can cause the cloth hardening and become airtight, and this coating just can come off after after a while, and is therefore also very undesirable.
And the part of sunlight during infrared rays, its wavelength is the 0.75-1000 micron, can't see that with human eye 15 centimetres of the far infrared rays porous inside of human body of its medium wavelength 4-14 micron begin heating internally, can promote microvascular expansion, make blood circulation smooth and easy, reach the purpose that enhances metabolism, and then increase the immunizing power and the curative ratio of health, therefore wavelength is called fertility light again at the far infrared rays of 4-14 micron, is the best with the far infrared rays of wavelength about 9.36 microns especially.Because far infrared also has deodorization, drying, dehumidifying, antimicrobial effect, therefore, be used as clothing or other warming articles for use again, very suitable.
Nantong Polytechnic College (Chinese patent 200420062599) adopts the method with carbon fiber wire and common yarn blend, electric heating is converted into ir radiation, thereby obtains the infrared heating fabric, but cost is higher, and certain application limitations is arranged, and is difficult to promote.Use particle to add in the polyester again in the patent 200310122001 with heat accumulation function, through spinning, be woven into the accumulation of heat infrared fibre, but in this patent not about the technology contents of the production of large-scale industry, lack the application of industry.
